Subject: Re: Two Displays on a 3/60FC
The 3/60C also has the Prism hardware in it (10 planes; 8 color, 1 B/W,
and 1 enable) so you can also have two window systems on the same physical
screen (one in the color planes and one in the B/W plane). I'm doing that
with two different NeWS servers now. The name of the B/W plane is
/dev/bwtwo1. If anyone wants an example of how to set all this up to
automaticly happen on NeWS startup, send me mail.

Don't you want WIN_CONSUME_KBD_EVENTS? Are ASCII events even defined for
the pick input mask?

That's backwards (see Table 18-15 in the programmer's guide).

That's because panel items aren't windows. So WIN_* attributes don't
apply to them. (This wasn't at all clear to me my first time through the
manual.)
You didn't include your code, so it's hard to guess what's going on. But
my first stab would be to say that you're using {panel,window}_get
operations on objects which don't have them defined. (Something that the
compile- and run-time environs will silently let you do.) "window_get()"
works on windows--that is, frames, canvases and panels, tty's and
textsw's--"panel_get()" works on *panel_items*.
> I should point out that I can't seem to find a clean way to find out if

Here's some code from a program I'm working on that (I think) does roughly
what you want:
The panel gets defined as:
window_create(RILframe, PANEL,
PANEL_ACCEPT_KEYSTROKE, TRUE,
PANEL_BACKGROUND_PROC, RILkeys,
PANEL_EVENT_PROC, RILkeys,
0);
just like yours. Then, in the event proc, when I need to know where the
event came from (in this case, I only care if it's a menu button event) I
find out if it's a panel_item, and if it is, I find out its parent (via
panel_get()) and use that instead:
RILkeys(panel_or_item, event)
caddr_t panel_or_item;
Event *event;
{
int curr;
switch (event_id(event)) {
case MENU_BUT:
/* This may be a Panel_item. Check and get its dad if it is. */
if ((Window_type)(window_get(panel_or_item, WIN_TYPE)) != PANEL_TYPE)
panel_or_item = (Panel) panel_get(panel_or_item, PANEL_PARENT_PANEL);
menu_show(mainMenu, panel_or_item, event, 0);
return;
case 13:
window_return(TRUE);
return;
[.
.
.]
}
panel_default_handle_event(panel_or_item, event);
}
Notice that this works because the typedef's of Panel and Panel_item
happen to be the same (that is, caddr_t). Notice also, that
window_get(panel_or_item, WIN_TYPE)
is technically illegal if the 1st arg is an item (since window_get() on a
non-window is a no-no), but thankfully it seems to always return a 0 (well
actually, ATTR_PKG_ZERO) in this case.
Hope this helps.

Subject: Re: cua0 configuration
Reference: v6n43
When I read Ron Hitchens' <vixen!ronbo at cs.utexas.edu> assertion in v6n43
that you can't dial in & out on the same line, I was greatly confused,
beacuse we have been successfully doing just that (dial in & out on one
line) simply by following the instructions in section 5.4 of the System
Administration manual. Then John Gardiner Myers <jm36+ at andrew.cmu.edu> in
v6n52 said it works fine as long as your modem doesn't assert Carrier
Detect (CD) all the time.
I have a possible explanation for why dial in/out won't work on some
systems. If you are using a Systech MTI (16 line mux, device mti[n])
port, instead of a CPU port (device zs[n]), you must use a special cable
to connect the modem to the port, as explained on page 149 of the System
Administration manual (Rev. B of 17-Feb-86). The same info also appears
on pages 19-20 of the Installation & Service Manual for the MTI board (Sun
part 813-1004-05).
The special cable connects pin 8 from the modem to pin 6 of the port. The
Systech board apparently uses pin 6 (DSR) to tell when the connection is
active/ready instead of pin 8 (CD). Most modems assert pin 6 (DSR)
continuously as long as they are powered up. If you used a straight
through cable to an MTI port, it would think a call was active all the
time, leading to the behavior observed by Hitchens. If you use the
special cable, everything works.
I consider the need for special cables to be evidence of brain damage in
either the Systech board or the mti driver. Needing special cables is
absurd. I thought the use of the various RS232 signals was settled many,
many years ago.
RTFM, every * page & line.

another theory is that since bill joy often types e-mail without use of
the shift key, the 'r' default makes sense.
[[ Uh, huh. And his car's dashboard has no gauges and only one idiot

this holds only if he doesn't want the wide audiences in private

now that there's a lot of traffic at&t<->sun, and since it is well-known
that bell labs tends to memo-heavy with wide distribution lists, there's
undoubtedly much action on these keys.

Subject: Multipartition Dump On Single Cartridge Tape
OK, here's the dump script I use to get multiple disk partitions onto a
single cartridge tape. Note this covers 2 70Mb disks, configured roughly:
sd0a -- 7.5 MB /
sd0g -- 42 MB /usr2
sd2c -- 65 MB /usr
and requires a total of two tapes.
------------------------ cut here -----------------------------------
echo Insert Tape Set for /dev/sd0a and /dev/sd0g, please. Hit
echo -n return when ready.
read dummy
dump 0ucfsb /dev/nrst8 3825 1750 /dev/sd0a
dump 0ucfsb /dev/nrst8 3825 1750 /dev/sd0g
mt -f /dev/rst8 rew
echo Insert Tape Set for /dev/sd2c, please. Hit
echo -n return when ready.
read dummy
dump 0ucfsb /dev/rst8 3825 1750 /dev/sd2c
------------------------ cut here -----------------------------------
Note the use of st8 to get QIC-24 format, and the large blocking factor.
The first increases the density and hence the capacity of the tape, the
second radically improves throughput. Both of these ideas were something
we picked up thru SunSpots.
In theory st8 will hold up to 60Mb. Practice says it's somewhat smaller
-- when sd2c is particularly full it requires a second tape.
There is some small risk that sd0a+sd0g will overfill a tape. It's never
happened to me, but your mileage may vary.

Subject: BIND on a Sun 3/180 with 3.5?
Hi group.
I'm trying to build Berkeley BIND 4.7.3 on a Sun 3/180 with 3.5 source.
Maybe this is my mistake. Not sure. I NEED BIND and am having REALLY BAD
times doing something about it. Some of the problems I face are:
o Sun UNIX and Berkeley UNIX are close but not the same. I keep
finding that BIND's makefiles want things Sun doesn't haveor has
in a hidden place.
o Sun seems to have consolidated some things that the BIND
makefiles want separated.
o What little BIND documentation there is has errors and isn't
very helpful to a UNIX novice.
o It takes too long to figure out which, if any, of the above is
the problem.
H E L P ! !
please
After three weeks I THINK I've MAYBE built /lib/libc.a but aren't sure.
Anyone who has built Berkeley BIND 4.7.3 or whatever on a Sun 3/180 with
3.5 please contact me. I need help!

Subject: Experience with 3rd party service on Sun equipment?
We are considering going to 3rd party service on our Sun equipment, mostly
because Sun won't cover so much of what we are planning to buy (8mm tape,
3rd party drives, etc.). We've been real pleased with the service (on
hardware anyway) that we've gotten from Sun (good response time, minimal
down time, etc.) and we're a little leery of 3rd party service. Thus we
are seeking the experiences of others who are currently using (or have
used in the past) 3rd party service vendors (we are primarily looking for
maintenance contracts equivalent to Sun's "on-site" level). We are
especially interested in anyone's expereince with Motorola Service, as
they are claiming to have exactly what we want.

Are the Sun 3/50 and 3/60 SCSI interfaces in some way inherently limited
to two disk devices? It appears that Sun only sells configurations with
zero, one, or two, but what would happen if I attached three expansion
disk units to a 3/60?
Is there:
a hardware (controller/other) limitation?
a problem with the cables in Sun SCSI disk expansion boxes?
a problem with terminators?
a software limitation?
no problem at all?

Subject: using line drawing characters?
I am new to the sun world (sun-light?) and am trying to port a program
over from the pc to the sun. The program uses pc line drawing characters
quite a lot. I thought no problem - ill just use the pcfont character
set. BUT - a little test program that displays all characters from 0-255
shows nothing above 0x7f. In fact the alpha characters repeat, which
leads me to believe that there is some sort of parity manipulation going
on (masking off the high bits). The question is how can I make the line
drawing characters show up!!!
Any hints, code fragments etc will be apprieciated. I've tried different
stty settings to no avail.....
